A STAND FOR TESTING VERTICAL-TAKEOFF-AND LANDING AIRCRAFT MODELS,

Abstract : The stand for testing VTOL vehicle models consists of a horizontally adjustable base with airlines, on rails, a revolving disk with toothed rack, a hollow holder coupled to the hinged frame with a counterweight, and electric drive. In order to increase the accuracy and reduce the costs of the experiment, it has a revolving disk hinged to the base, while the holder is C-shaped; the lower end of the holder is attached to the ejector and the model is attached to the top so that it is possible to line up the model's wings in the plane given by the experiment program.
